1. Good rigidity, precise positioning, high synchronization, self-locking
4. Easy to install, save time and effort
The rack and pinion drive elevator can transport people and goods.It is mainly composed of tower, fence, engine compartment, driving device, control system, sectioning device, safety device and lifting system.
Compared with simple elevators, rack-and-pinion-driven elevators have the characteristics of large height, fast erection speed, safety and reliability, and dual use of human and cargo. They are widely used in building construction, especially high-rise building construction.
A pipe truss structure composed of several standard sections.In order to ensure the stability of the tower, the attachment rods are used to connect with the building once every certain height (about 10-15 meters).The tower section is equipped with racks and guide rails.
2 Carriage and fence
When the carriage descends into the fence, the door opens automatically, and when it rises, the door closes automatically.To ensure operational safety.The bottom of the fence is equipped with a spring buffer device.Avoid impact when the machine is on the ground to ensure a smooth shutdown.The cabin is a container for carrying people or goods, and the fence is a device for enclosing the cabin and the tower, and is located at the bottom of the tower.Mechanical-electrical interlocking for cabin door and fence door.
3 drive device
The section-adding device is located on the top of the cabin, and is a manual or motorized small boom crane.When the section is added, the carriage rises to a certain distance from the top of the tower, and the standard section to be added is hoisted to the top of the tower by a crane. After it is fixed in place, the sectioning process is completed.In order to ensure the safe operation of the elevator, it is equipped with a speed limit braking device, a travel limit switch, a door protection switch and so on.It is located in the engine compartment and consists of a motor, a reducer and a rack and pinion.The gear at the output shaft end of the reducer extends out of the engine compartment, meshes with the rack fixed on the tower, and moves the engine compartment up and down.There is a control system in the cabin, and the operator can also run randomly
